View source for Sapelo2 changes after Jan.25 maintenance


During the Jan. 25-26, 2022 Sapelo2 maintenance, the Slurm queueing software was updated to version 21.08.5.

Changes needed in the job submission scripts:

1. If your application/program uses the MPI libraries listed below, please run the binary with '''srun''' instead of '''mpirun''' or '''mpiexec''':

*OpenMPI versions up to 3.1.4 
*foss/2019b and fosscuda/2019b toolchains
*Intel MPI provided by the intel/2019b and intel/2020b modules

2. If your application uses MVAPICH2 (e.g. MVAPICH2/2.3.4-GCC-8.3.0), please run the binary with '''srun --mpi=pmi2''' instead of '''mpirun''' or '''mpiexec'''.
